Seating Choice versus GPA (Stacked & Split Columns for Front & Back Rows)
This dataset contains hypothetical (I believe) data on GPA for students who sit in the front and back row of a classroom. The data are shown in several ways: (a) two separate columns (one for the front row GPA and another or the back row GPA); (b) stacked with one column to indicate front or back row and another column with the GPAs; and (c) the row column repeated as a 0/1 indicator variable.
This dataset is useful for comparing the different ways that StatCrunch can compare the means of two groups: (a) The two columns of scores (front and back) can be used in the 2-sample t-test or a one-way ANOVA; (b) the stacked text column (front/back) with a separate column for GPA can also be used for one-way ANOVA; and (c) the 0/1 indicator column and stacked GPAs can be used with correlation and regression. Every procedure gives the same p-value and same conclusion, thus highlighting the similarity of statistical procedures and StatCrunch's flexibility. | yes | bartonpoulson | Apr 08, 2010 | 465B | 110 |

Crime: Walmart vs. Target
This data set comes directly from the "Is Wal-Mart Safe?" report. Are you tempted to do a paired t test to compare the mean number of police incidents at Walmart to the mean number of police incidents at Target? This was actually done in the report. I think this is a bad idea because only the Walmart stores with high incident reports were considered. See the excerpt from the report in the comments below. | yes | websterwest | Feb 29, 2008 | 3KB | 593 |
Who's the greatest president?
This data set contains the results of the Zogby Presidential Greatness Poll over the years from 2006 to 2008. The survey each year contains the results from 1026 likely voters. The Positive column shows the proportion of those surveyed that think the president was great or near great. The Negative column shows the proportion of those surveyed that think the president was below average or a failure. | yes | websterwest | Feb 28, 2008 | 1.012B | 139 |
